Application Flea Novemberjla, 1925. Serial No. 69,972.

My invention relates to a can conveying inverting and discharging mechanism, an an object of the invention is to provide ecient means for conveying and properly inverting the can back to its upright" position after the can has travelled through the washing machine in its upside-down position; another object is to provide means which may be variously arranged and adjusted for delle livering or discharging the cans in a selected or certain one of several directions; and another object is to provide afgravity platform which may be variously arranged on the mechanism, and-Which has means for adjust- 116 ing its inclination, so as to transfer cans from the inverting means in one of several directions. y

@ther objects will appear hereinafter.

rlhe invention consists in the combination an and arrangements of parts hereinafter described and claimed.

y The invention will be best understoodby reference to the accompanying drawings forming a part of this specification, and in at which,

rlhe form of invention illustrated in the drawings briey comprises means for conveying the can in its inverted or upside-down position through the washing and cleaning machine; also means for tilting or invertin the can back into its upright position; an means for receiving the inverted vor tilted can and for d'nscharging it in a selected one of several directions.

titi

The means for conveying the can comprises a supporting frame 15 with stationary rails 16 fastened thereon for slidably sup port-ing the cans 17 thereon as indicated in the drawings. A. guard rail 18 is mounted with bolts or members 19 on the main frame 15, slightly above and outward of the supporting rails 16, as best shown in Figs. 2 and 10. A rail 20 is mounted on the frame, ad-

jacent the rail 16, for slidably supporting the cover 21 thereon, and a idc rail 22 is mounted with bolts or mem ers 23 on the main frame, to engage intermediate the side of .cover 21 for guiding the same, as best shown in Fig. 10. Track means24 extends from track 20 to the discharging means, and a guide rail 25 extends from guide rail 22 likewise to the discharge means ot the machine, as best indicated in Fig. 2. f

The means for actuating the can to ad varice them in a step-by-step' movement through the washing machine 26 comprises a pair of bars 27 having tripiingers or pawls 28 pivotally mounted thereon and having strips or plates 29 provided at the inward Said bars 27 are preterably in" the form ci angle bars reciprocated onrollers 30 mounted on shafts 31 supported in the mainframe 15, as best shown in Figs. 2 and 9. The means for moving the covers 21 simultaneously with the cans includesm bar 32, which is preferably an angle bar and reciprocates on a roller '33 mounted on said shaft 31.` 'llrip lingers or pa'wls 3d are pivotally mounted with pins on said bar 32.

An operating lever 36 is tulcrumedA on a bracket 37 on the main frame 15, and has on its lower end a pivot pin 38 engaging in i said bars 32 and 27 being fastened together by means of a cross bar 41' or the like, and the movement of the handle 36 thus reci rocates the bars 27 and 32 with their attac ed trip fingers or pawls 28 and 34, to intermittently move the cans and the covers forward.

The means for tilting or inverting the cans referably comprises a swingable means inclu ing a pair of curved members 42 shaped to receive and hold the cans therein, and members 43 of rubber or` other suitable pliable frictional material are mounted at the ends of the curved members 42 for4 closely engaging and embracing the can and preventing the same from slipping out of said curved members during the initial swinging or rotatin thereof. F langes 44 extend inal paralle direction from members 42 and are fastened together byy boltsk 45 and by rods 46 which are arranged in semi-circular form adjacent the outer edges of said flanges. The tiltin means is swingably mounted by means o a pivot member 47 which has its ends 47 journalled in a bearing 48 mounted with a bracket 49 on the supporting members 15 which extend from the main frame 15. A holding flange or plate 50 is provided at the ends of members 42, opposite the fritional members 43, to

revent the can from sliplpin longitudinally rom/the frame during t e nal 'part of the swinging movement of the tilting means. :A rack bar 51 K,engages the rods 46 for swinglng the tilting or inverting means, and said rack bar is supported at its forward end` on a roller 52 ivoted with a pin 53 in bracket means 54 astened to supporting members 15. The rear end of said rack ar is provided with forked members 55 which are fastened with bolts 56 or the like. to' the re-" ciprocatin members 27, as best shown in F1 s. 2 an 5. e

he means for advancing and discharging the cans delivered by the inverting means comprises a frame 57 fastened to the ends of the supporting members 15', and supported on legs or supportingl means 58, as best shown in Figs. 5 and 7. A4 avity conveyor or latform 59 is mountable; on the frame 57 in various positions, and has rollers 60 provided thereon. Threaded members 61 extend upwardly through frame 57 and enga e the flowerw part of said platform 59, an said threaded members are adjustable so as to give said platform the desired inclination to permit the can to travel over the .platform at a proper rate of s eed..

Plates 62 are also provided on the plat orm for convenient engagement by the hand to rearrangethe plat-form on t e frame, and

"flange members 63 are provided on the frame to retain the platform in proper position thereon.

lThe latfdrm 59 may be arranged with the ro ers extending transverselyy of the main frame 15, said frame being inclined longitudinally of said main frame, as indicated in Fig. 1 of the drawings, to advance the cans longitudinally or axially of the main frame; or the platform may be arran ed and adjusted so that the rollers exten lon 'tudinally of the main frame and theJplatflrm is inclined towards one side of said main frame, as indicated in Figs. 2 and 7 of the drawin s, in order to move the ans towards one side of the main frame, and when thus arranged a guard bar 64 may be used and mounted in opening 65 on the frame 57 to prevent the cans from sliding longitudinally of the rollers and falling therefrom, and to assure their movement laterally or transversely of said main frame. The platform 59 also has its side bars extendin suiciently upwardly so as to receive t e bottom of the can as it slides from the tilti means, in an inclined direction, as indicate in'Fig. 5, and thereafter the can automatically moves onto the rollers in its `ipright position and is automatically moved y t rollers.

Discharge means, or a further gravity conve or is arranged to be mounted on either si e of frame 57, in harmony with the arrangement of the platform 59 on said frame, as variously indicated in Figs.y 1 and 2, and this dischar g meansy preferabl comprises framegkirs 66 with rollers 6; rotatably mounted therein and with guide bars 68 extending' upwardly above said frame bars. Hooks 69 are provided on said frame bars 66 to en age over and on the side [langes 57 of drame 57, as best' shown in Fig. 7. This `discliargin means may be mounted at the rear en of frame 57 or maybe mounted at the/side of frame 57- to discharge in harmony with the arrange ment of p atform'59 on said frame 57, and to discharge the cans either longitudinally e force of gravity along the inclined y from the end of the main frame lor transversely to vone side thereof.

while i have illustrated and described die preferred form of construction for carrying my invention into effect, this is capable o variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction setfforth, but

esire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

. 1. A device com risin means for conveying a can, means or` t' ting a can, and ad- Meme means sind Whereand a rack bar attached to and moved with seid reciproceting means, swingable means 1U having rods arran ed in a semi-circle eingaged by said rac bar for' swinging se@ means and inverting the cans.,

Y ln testimony whereof l have ysigned. my

name to this specification.
